I had an attachment to mount my light by the mid-fork braze-on. The light went back to the handle bar after a week.
Makes sense. The lack of braze-ons such as cable guides and bottle mounts is normal for 70s and some early 80s frames. I tired to ID the dropouts because the little hole protruding into the triangle is unusual. No luck though, maybe CV and get it.

Why do you say stamped? They look like any other forged dropouts brazed into the stays. I can even make out the threaded holes for adjuster screws, usually seen on good quality bikes.

Good eye, didn't see the adjuster screw threads at first. So, if they're forged dropouts without a derailleur hanger, then the frame is either a unique 1970's fillet brazed steel frame, or something more modern with a pretty ambiguous intended function (I'm still thinking coaster brake or other internal gear hub).

Looks like the rear spacing is oddly about 105mm. It doesn't appear bent. Even if the dropouts were bent...15mm bent?

...that's a lot to spread to get to 120mm. What the heck is this thing??

Try posting in C&V, and maybe target T-Mar or Randyjawa.

Are there scratches circling the NDS chain stay approximately 4 inches forward of where the axle would be? No brake bridge and 105mm spacing, these point to a coaster brake bike. The scratches would be evidence of a reaction arm being clamped there.

I would think a coaster brake bike would have low quality stamped dropouts.

Thank you. I posted the link on C & V. All this said though, I'm thinking of a repaint, making it a fixie, and selling.

IDK. Maybe you know something that I don't, but I've never seen a coaster brake hub with an OLD anywhere close to 105mm. All of mine have been 120mm, and the smallest I could find on the interwebz is 116mm. Maybe it's an old njs keirin frame with a 110mm fixedgear wheel spacing (not serious).

Were yours older models? What brand? I ask because all the modern Shimanos (CB-E110) and KTs and SAs are 110mm OLD. IIRC even my old Bendix hubs and Stingrays were 110. The frame being off at 105 would not be uncommon for a low budget coaster bike. All the cheapo bikes that I have owned have had spacing that's been off a few mms one way or the other.


Sheldon says...

You'd be hardpressed to get a paintjob as nice as the one that's on there already.

You'll fetch better offers with the paint that's already on there vs what I'm going to assume is spraypaint. The paint on that frame definitely has character.
Try applying car wax and buffing.

Well, honestly, I never measured the spacing on my older coaster brake bikes like my Koss Cruiser, so I can't say for sure that they were not 110mm. The only coaster brake bike in my current stable is a SE Draft Coaster with a Shimano hub, and it measures about 115mm, although the reaction arm is stamped CB-E110, which suggests that the hub might be available with 110mm spacing. So, I will defer to your coaster brake expertise.

My antique Campagnolo catalog has data for the matching crank chain-line BB spindle,

for a 110 wide hub/frame spread..

there are short width Sturmey Archer 3 speeds too..

Of course bought online then shipped Who knows what bending took place.
the frame have a spreader block in the dropouts when you opened the carton?



?

That is true about the paint. I may just leave it alone. Although my buddy does have a body shop and could have him paint it the same color as whatever car is in the booth at the time.

Something I have spotted in person with a Bikes Direct bike (Windsor) and an LBS that has a fleet of aluminum cruiser rentals. The hubs are spaced out differently than stock trim to accommodate different frames. It's achieved, obviously, with extra (or thicker) washers in between the cone and locknut on the drive side and in between the reaction arm and locknut on the NDS. The Windsor had two 4mm washers to fit the 118mm spacing. The hubs aren't supplied that way by Shimano, so it's gotta be the wheel factory making modification to suit customer specs.

Yers, they look rather like Milremo dropouts with the derailleur hanger amputated:



"Milremo" was André Bertin and Ron Kitching's house brand, and the dropouts were used on their own bikes as well as available to third-party builders.

That certainly looks like the rear dropout. Fork crown does look different though.

not a fan of a 'cheap' frame with chains hanging like that, no matter what it is.

I do not think I can stand that poor quality paint as seen in the most recent photo. I plan on making this a single speed, bright red, with a straight bar (already have), red and black tires (already have), and single speed sprocket (mail order). I am unsure if I should build up the black Velocity rims I have hanging or use the black Forte Titan rims I also already have.

Almost finished...

What happened to bright red?

Too much work. I changed my mind.

In this case, it obviously means a lot of "fix-ing"....
